I was experiencing the same problem in Ubuntu 14.04. I assume the problem was related to the /lib64/ld-linux-x86-64.so.2 symlink as described above.
As a workardound to avoid booting into live-cd I just replaced the link with ln -sf: ln -sf /lib/x86_64-linux-gnu/ld-2.17.so /lib64/ld-linux-x86-64.so.2 Valgrind now appears to be working normally. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247026 Title: valgrind does not work on amd64 (strlen missing) To manage notifications about this bug go to: https://bugs.launchpad.net/valgrind/+bug/1247026/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
